-- for defining several iostreams template classes that manipulate exteral files

fstream is a standard C++ library that handles reading from and writing to files either in text or in binary formats.

Provides facilities to manipulate output formatting, such as the base used when formatting integers and the precision of floating point values.



process.h is a C header file which contains function declarations and macros used in working with threads and processes. Neither the header file nor the functions are defined by either the ANSI/ISO C standard or by POSIX. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library.
